Emergency surgery: half a day does make a difference.

The emergency operating patterns in a district general hospital were significantly altered by the introduction of an afternoon emergency theatre list co-ordinated by a consultant anaesthetist. Before the introduction of the list, 88% of emergency operations were carried out after 17.00, with 40% of cases waiting until after 22.00. Introduction of the emergency session significantly reduced the operations performed after 17.00 to 53%, with only 12% being delayed until after 22.00.
